Yes. Mosses usually grow in damp and shady locations like at the base of trees and edges of water bodies. But some species can also grow in alpine rocks and sand dunes.
Spanish moss
Moss does not move but it does have roots that make it stay in the ground and it usually grows on the sides of wet trees.
Liverwort
The moss itself does not effect plant growth directly. But, moss grows in soil with low pH, and the moss will hold water in the soil which is USUALLY good. Moss grows in soil that is shady, wet, and doesn't have good drainage, so areation would help along with a dose of lime. Follow the link below for more detailed info. Hope this helps, Kevlarster

The green moss was most slippery when it was wet.
The moss that grows on rocks is considered a form of mechanical weathering. The roots of the moss penetrate the cracks and crevices in the rock, causing physical breakdown through expansion and contraction as the moss grows and shrinks. This process eventually breaks down the rock into smaller fragments.
Moss does not point to anything. There is an old wive's tale that it grows on the north side of trees, but actually it grows all over.
